It will be -Aseen that-the cables connect-ing` 'the'pulleysjvvill be'maintained' taut byY the Iprovisionof thev springs, and Vsince eachpipe `'line is supportedupon the smooth flat pla-'nes 34,frictional-opposition to the turningofthe line will be reducedto aminimum, andcons'e# quently, the ,available ,power ,of each oscillajytor18 is efficiently utilized and one such oscilf- `lator is-.enabled' toA'turn a plurality of pipe rlines, Whereas heretofore it-hasbeen custom'aryl toy install kone yoscillator foreach -line or, obviously, oneoscillator Willv be. adapted to turn a much'longer length of pipe *lineAthanA Y has` heretofore'` l been .regarded asi-possibleV owingtoelimination. ofk friction lon ythe bearl ligure 3 line 11', for example,as rit rollsuponone'of its Alsupporting'members737, thepositions whichillustrates the'pos'ition' of the pipe ros the pipe 11 takes beingindicated by dotted lines. As a matter Vof fact, each pipe line will beoscillated so that the apertures 13 will travel through an arc equal toapproximately a third of the circumference of a circle, this Y amount ofoscillation permitting themaxi- V mum spread and distribution of thespray issuing from the apertures 13.

It will be apparent that installations of this character will veryeconomically and eficiently irrigate a desiredarea` for as long an-`interval and as frequently Vas may loel desired; and since it will beapparent that the points of friction between the pipe lines andthe sup-Y porting members are reduced to a minimum, the effort required by agiven oscillator to turn the lines is reduced to a minimum, andtherefore, the available power of a given oscillator can be utilized inthe eiicient operationV of a number of pipe lines instead of beingconsumed in overcoming frictional engagement between a line and itssupporting members as has heretofore been the case. It will also beapparent that While the above yspecifically illustrated and describedembodiment of the invention represents atypical form of installation, itwill be apparent that changes in details thereof may be made withoutdeparting from Vthe inventiveconcept; and it .30 will be accordinglyunderstood that it is intended and desired to embrace within the I scopeof this invention such modifications and Y changes as may be required toadapt `it to varying conditions and uses; y'

Having thus described my invention, what Y I claim as new and desire tosecure by Letters Patent of the United States, is- Y An irrigationsystem comprising the combination with a plurality of apertured pipe 40lines adapted to deliver a spray of liquid therefrom, each of saidpipelines having a pulley iXed thereto, the adjacent pulleys be-V ingconnected by individual cables, springs interposed in said cables tomaintain the same taut, and an oscillating means for turningA one ofsaid pipe lines through a predetermined angle, thereby turning all ofsaid pipe lines through said pulley and cable instrumentalities touniformly distribute the liq-` .50 uid spray therefrom,'of a pluralityof supv porting means for each pipe line, the said supporting meanscomprising a plurality of brackets having a smooth, straight flatpipesupporting edge along which the pipe is adapted to roll with a minimumof friction, each of the said brackets being provided with means forreadily removably Vsecuring the bracket in a holder with the said pipesup-` porting edge in a horizontal plane, said means 6c including aprojection extending from saidv bracket and frictionally engaging saidholder.

In testimony whereof I afix mysignature.
